To find the percent decrease, we need to find the difference between last year's enrollment and this year's enrollment, divide that by last year's enrollment, and then multiply by 100.

Difference = 8000 - 2000 = 6000
6000/8000 = 0.75
0.75 x 100 = 75%

Therefore, the percentage decrease in enrollment is 75%. To find the percent decrease, we need to find the difference in enrollment (which is 8000-2000 = 6000) and then divide that by the original enrollment (8000) and multiply by 100 to get a percentage. So, the percent decrease is (6000/8000) x 100 = 75%. Therefore, the correct answer is choice C.
